Hi all,
I have latest OMV4 with Odroid HC2. Everything is fine with it except that I haven't any CPU usage statistics in my Performance statistics.
I disabled and enabled the Monitoring in the System menu but same result.
Here is an image about the my problem
Do you have an idea why isn't?
Thanks for your help!

It's the other way around. As soon as you enable monitoring and still run off SD card you have a problem. Enabled monitoring results in constant writing of small data chunks to the rootfs with an ugly high Write Amplification. Your SD card will wear out pretty fast.
Thought the flashplugin was made for exactly that

The flashmemory plugin takes care about some directories with high write activity. Simply to check using 'df':

root@raspberrypi:~# date
Mon Jul 30 11:01:42 UTC 2018(I added this code to armbianmonitor a while ago to monitor exactly that --> write activity below the filesystem layer to get a clue how writes at the flash layer might look like)

Thanks for your answer!
So in your opinion I should rather turn off my Monitoring to keep a longer life time of my SD card?
